Sharing Docs with delegated email

[TomVarndean]

Hi,

I'm looking for ideas from the community. Departments in our organisation have delegated access to department email addresses which they have used for years, but now more and more staff are sharing Docs with this account and they cannot access them as they have not been shared with their individual accounts.

Without changing how these teams work, is there a way we can use Google Groups, or email aliases, or something else, to automatically give permissions to these people when someone shares with Doc with their department email address?

Thanks in advance for your ideas
